Definitions

  • the present invention relates to an applicator for attachment to a pressure container, and more particularly but not exclusively for a handheld applicator for attachment to an aerosol can.
  • pressure containers or pressurised containers
  • aerosols and foams are supplied in various products or compositions.
  • One application for these products is in the construction industry, including DIY, for example where polyurethane (PU) foam is useful to fill crevices and provide insulation.
  • PU polyurethane
  • Some glues and pastes are also available in pressure containers.
  • the pressure container is usually cylindrical and made of a metal which can maintain its shape whilst containing the composition at pressure.
  • a valve is provided at the top of the container. Pressing or operating the valve causes an outlet to open, followed by some of the composition exiting the container under pressure.
  • the composition may disperse, expand or react with the air, or a combination of these.
  • An applicator (or applicator gun) is often supplied separately to the pressure container and requires the end user to correctly fix the applicator to the pressure container.
  • the pressure container is often inverted for use, with the applicator at the bottom.
  • the applicator can be made of a combination of metal and plastic. Often the applicator is a very basic device which is difficult to use and ergonomically inadequate when attached to a pressure container or can.
  • US10106309B2 to Soudal describes an applicator which in some ways improves on a conventional applicator.
  • the applicator is supplied to the end user as part of the pressure container, rather than the end-user needing to attach it themselves.
  • the applicator cannot be removed from the pressure container by hand.
  • the applicator in US10106309B2 has a pistol grip, with a ridged grip surface and a moveable trigger having an integral connection for a hose, where the connection projects beyond the moveable trigger.
  • the pistol grip forms the back and sides of the applicator, whilst the trigger is a narrow piece at the front.
  • a safety seal is provided so that the trigger can be secured against movement.
  • a hose can be attached to the connection to help control where the composition is to be applied.
  • the safety seal flapped open the trigger portion is squeezed towards the grip surface. This causes the valve on the pressure container to open and dispense composition.
  • the safety seal can be a nuisance during use. If the safety seal is not closed properly after use and the projecting end of the connection is accidentally knocked, this can inadvertently open the container valve and dispense some composition from the pressure container.
  • an applicator for attachment to a pressure container, the pressure container comprising a composition and a container valve, the applicator comprising a cap portion for fitting to the pressure container over the container valve, the cap including an aperture for receiving a nozzle piece, and a body arranged around the aperture on a first side of the cap, and a handle for a person to grip the applicator, the handle comprising first and second handle portions connected to the cap and extending away from the aperture to a second side of the cap, the handle portions being spaced apart on opposite sides of the aperture on the second side of the cap, the first handle portion being moveably connected to the cap for operating the container valve, and the second handle portion having a substantially fixed position relative to the cap, characterised in that a tab is provided between, or releasably secured between, the first and second handle portions, in a first configuration the tab being engaged with one or both handle portions and extending through the space between the handle portions to substantially prevent movement of the first handle portion towards the second
  • the invention provides a gun-trigger type device which can be attached to an aerosol can or another suitable type of handheld pressurised container.
  • the applicator can be used one-handed for dispensing the contents of the container in a particular direction.
  • the contents may include Pll foam or any other composition suitable for dispensing from a handheld pressurised container.
  • the applicator may be considered as an all-in- one dispenser, particularly once assembled to a pressure container.
  • the tab prevents the container valve being inadvertently opened prior to sale and use by an end user, but is easily detached or removed for use.
  • the applicator can be supplied pre-attached to a pressure container, providing a safe, ergonomic and ready-to-use device for the end user, whether they are a DIY user or a professional tradesman.
  • the applicator (including the tab, whether or not still attached) can be easily detached for recycling or attachment to a new pressure container having a suitable connection, typically once the existing pressure container has been emptied of its useable contents.
  • the applicator can also be supplied as a discrete item, independently of a pressure container, which is easily attachable to a pressure container and subsequently easily transferrable to another pressure container.
  • the cap preferably includes a threaded connector for connection to the pressure container.
  • the threaded connector may be disposed to the first side of the cap for releasably connecting the applicator to a corresponding thread on the pressure container.
  • the cap may include a snap-fit connectorfor snap-fit connection to the pressure container.
  • the cap may include a lever or release element for releasing the snap-fit connection to remove or ease removal of the cap from the pressure container.
  • neither the lever nor the release element is essential for disconnecting the snap-fit connection.
  • the screw or snap-fit connections allow the applicator to be easily unscrewed or detached from the pressure container, preferably when the pressure container is empty or has little useable composition remaining. The applicator may then be recycled, or attached to a new pressure container.
  • the lever or release element may be part of the cap.
  • the lever may include a plurality of frangible connections to the rest of the cap.
  • the lever may include a distal end which extends beyond the maximum extent of the rest of the cap. That is, relative to a plane meeting a base of the cap, the lever may extend through the plane.
  • This provides a handle or lip that can be used to lift the lever whilst the rest of the cap is snap-fitted to a rim on the pressure container, thereby weakening the connection and allowing the applicator to be disconnected from the container. Having the lever extend below the rest of the cap, and so below the container rim, such that it is easily used is preferred, but it is also envisaged that other means could be employed such as a ring-pull type element on the lever.
  • lever is not necessarily to be construed in a functional sense, because the lever itself does not need to lever the applicator off the container.
  • the lever may be an elongate element which is hinged at one end where it connects to the applicator, thus resembling the shape of a lever. Lifting the lever upwards may weaken or break the snap-fit connection of the applicator to the container, allowing for applicator detachment without actually levering the applicator off the container. It is nonetheless envisaged that other embodiments may include a lever which may be arranged to in use impart a levering force, e.g. against the container, for detaching the applicator.
  • a force transfer element may extend from the first handle portion towards the second handle portion for operating the container valve.
  • the force transfer element may be considered to be a trigger or part of the trigger.
  • the force transfer element may be a projection extending from the second wall of the moveable handle portion.
  • the force transfer element may taper towards a central longitudinal axis of the aperture.
  • the force transfer element or projection may be elongate or may be substantially stub-like.
  • a distal portion of the force transfer element may be positioned partway between the first and second handle portions.
  • the distal end of the force transfer element may be in a position overlying the nozzle piece, which may be a nozzle end of the nozzle end.
  • the distal end of the force transfer element may be in a position substantially overlying the aperture and nozzle piece on the second side of the cap for operating the container valve when the first handle portion is moved or pivoted sufficiently towards the second handle portion during use.
  • the force transfer element may extend in a direction towards the nozzle piece.
  • the tab may be substantially planar.
  • the tab may be a tear-off tab in some embodiments.
  • the tab can be recycled once removed from the applicator.
  • the tab may have a plurality of frangible connections to either or both of the first and second handle portions.
  • the tab may extend between second walls of each handle portion, where those second walls may each partially span the chamber. The tab prevents movement of the first handle portion towards the second handle portion until the tab has been suitably disconnected.
  • the tab may be releasably securable between the handle portions, such that it can be removed for use of the applicator and then replaced between the handle portions. That is, the tab may be selectively moved from the first configuration to the second configuration, and also from the second configuration to the first configuration.
  • the releasably securable tab may include engaging means at one or both sides for re-engaging one or both of the handle portions.
  • a top of the tab may be substantially flush with a top of the applicator, or may be inset from the top of the applicator. That is, the tab preferably does not protrude above the top of the applicator gun. This applies whether the tab is a tear-off tab or a releasably securable tab.
  • the tab may be disconnected from the handle portion(s) by rotation about an axis which is substantially perpendicular to a central longitudinal axis of the aperture and which is substantially parallel to a plane of the tab.
  • the tab may be slidable from the first configuration to the second configuration. This allows the tab to be releasably secured in the configuration which blocks trigger action.
  • the first handle portion When slid into the second configuration, the first handle portion may be movable towards the second handle portion.
  • the slidable tab may include one or more detents for engaging corresponding portions of the handle portion(s).
  • the second configuration may involve the tab being completely detached from the handle portions.
  • the slidable tab may include a grip region.
  • the grip region may be at an upper end of the tab.
  • the grip region may include one or more ridges or knurling.
  • the grip region may include areas on both sides of the tab.
  • the grip region may be recessed into the tab on one or both sides. There may be a plurality of ridges.
  • the ridge(s) may be curved about an axis which is perpendicular to the plane of the tab.
  • the slidable tab may include a channel at one side, or a pair of channels on opposing sides of the tab.
  • Complementary rails or protrusions may be provided on one or both of the corresponding region(s) of the handle portion(s) for receiving the channelled part(s) of the tab.
  • the tab may therefore be slid out of the top of the applicator for using the applicator.
  • the tab can be inserted back into position between the handle portions by the reverse movement to block the trigger action.
  • equivalent complementary engagement means may be provided by providing rails/protrusions on the side(s) of the tab and corresponding channelled portion(s) on either or both of the handle portions.
  • a concave depression or area may be provided on the top of the tab. This is an ergonomic shape for pressing the tab into position between the handle portions.
  • the tab may have a substantially trapezoidal cross-section or perimeter. Corners of the tab may be rounded.
  • the tab may be substantially symmetrical about a central vertical plane bisecting the tab.
  • the tab may include a finger aperture (or finger-sized aperture) for either detaching the tab from or sliding the tab out of engagement with one or both of the handle portions. That is, the tab may include a ring-pull type element.
  • the finger aperture makes it quick and easy to disengage the tab.
  • the finger aperture may be disposed within the chamber.
  • the finger aperture may be disposed outside the chamber.
  • the tab may include a stopper or plug for fitting inside an open end of a straw, particularly when the other end of the straw is connected to the nozzle piece. This is particularly useful where the tab is a frangible or break-off tab.
  • the stopper or plug may be substantially cylindrical with a slightly tapered or conical end.
  • the tab may also include a pair of flanges or guides spaced to either side of the stopper. This provides a pair of recesses into the tab body which helps ensure the cylindrical part of the stopper is engaged in the straw, for preventing flow through the straw.
  • a nozzle piece may be disposed through the aperture of the cap.
  • the nozzle piece may include a conduit having an inlet disposed on the first side of the cap for connection to the container valve for receiving composition from the pressure container, and an outlet disposed on the second side of the cap facing towards the first handle portion for dispensing composition.
  • the inlet and outlet may be oriented substantially perpendicular to each other.
  • the nozzle piece directs the flow of composition from the chamber laterally from the applicator.
  • An elongate tube or straw can be connected to the nozzle outlet to better direct the flow.
  • the nozzle piece is preferably a separate element so that it can be releasably connected to the applicator. This makes it easier to recycle the applicator if the nozzle piece is made of a different material or if it is contaminated and needs to be disposed of.
  • the nozzle piece may be pivotably mounted to the applicator.
  • the nozzle piece may be releasably connected to the applicator.
  • the nozzle piece may include a pair of opposing rods for fitting to corresponding clips on either side of the aperture.
  • the nozzle piece may be pivotably to the underside of the cap.
  • a flange with a C-shaped or U-shaped cross-section may be disposed on the second side of the cap around the aperture for fitting around the nozzle piece.
  • the flange provides a type of shroud around the nozzle piece to prevent it from being accidentally knocked. This in turn prevents inadvertent opening of the container valve, which would waste some of the composition.
  • the nozzle piece outlet may be set back from the outer wall of the moveable handle portion for the same reason.
  • the first handle portion may include an aperture aligned with a gap in the flange. This may allow for a secondary conduit (such as a tube or straw) to pass through the first handle portion and connect to the nozzle piece outlet.
  • the outlet may be set back from the front of the applicator within the aperture of the first handle portion, or behind that aperture.
  • the distal portion of the force transfer element may be disposed on or adjacent to the nozzle piece for applying a force to the nozzle in the direction of the pressure container when the first handle portion is moved or squeezed towards the second handle portion.
  • the force transfer element or trigger can move when the first handle portion is moved.
  • the trigger may pivot into engagement with the nozzle piece, to axially depress the nozzle for opening the container valve.
  • the trigger may be arranged such that movement of the handle portion may cause translation of the trigger with the same result.
  • a first side panel may be releasably fitted between the first and second handle portions on one side of the tab.
  • a first chamber may be provided between or adjacent to the first side panel and the tab.
  • a second side panel may be releasably fitted between or adjacent to the first and second handle portions on the other side of the tab.
  • a second chamber may be provided between the second side panel and the tab.
  • Each chamber may be of a suitable size for receiving a pair of gloves or one or more other accessories.
  • the pair of gloves may be in a packet or sachet, for example.
  • the gloves or other accessory may be stuck or secured by an adhesive to an inside of the panel, for example.
  • the side panel(s) may also be re-fitted to the applicator after use as a stop for preventing movement of the first handle portion, and so preventing accidental dispensing of composition from the pressure container after tab removal or disengagement.
  • the side panels do not get in the way during use of the applicator because they can be fully disengaged from the applicator.
  • Either or both side panels may include a concave area which overlies the concave area of the tab.
  • Either or both side panels may have a window or central aperture.
  • Either or both side panels may have a skeletal structure.
  • either or both side panels may have a plurality of apertures or slots. This reduces the amount of material required for the side panel(s).
  • the side panels may be made of plastic.
  • the side panels may be injection moulded or vacuum formed.
  • the plastic thickness of each side panel may be in the region of 100 to 500 microns, and preferably around 350 microns thick. This provides ultra-thin, flexible side panels which, whilst structurally weak, minimises plastic usage and product weight. Vacuum forming is preferred to minimise side panel thickness.
  • the side panels may be made of a material selected from: paper, moulded paper pulp, cardboard, micro-fluted board (such as recycled micro-fluted board), or cartonboard, or another similar cellulose-based material.
  • the side panels may be provided as part of a single or unitary body.

  • the tab 122 has a finger-sized aperture 126 at its top end, and a thin strip 128 around the aperture for pulling the tab 122.
  • the tab 122 has an approximately triangular body portion below the aperture 126 for substantially complementing or accommodating the trigger 113b. The tab 122 can be manually pulled out of its plane to detach it from the handle portions 112, 114.
  • the tab 122 may in some embodiments be configured such that complete detachment is unnecessary.
  • the tab may slide out of position to detach it from either handle portion, or the tab may be hingedly moved out of engagement from one of the handle portions.
  • the key principle is that the tab 122 no longer bridges between the handle portions, and cannot therefore block movement of the moveable handle portion 112 towards the fixed portion 114 when the handle 104 is squeezed to dispense composition from the container 10.
  • the applicator 100 includes a central aperture 130 for the nozzle piece 120.
  • An internal thread 132 is provided in the underside of the cap portion, around the central aperture 130. The thread 132 complements the external thread 16 of the container 10 to provide a releasable connection between the applicator 100 and container 10.
  • the nozzle piece 120 is releasably connected to the underside of the circular cap top 102a by virtue of a pair of rods 120a fitting into corresponding clips 102b on either side of the aperture 130.

  • FIG. 6 An inlet end 120b and outlet end 120c are also best seen in Figure 6.
  • the inlet end 120b of the nozzle piece is cylindrical and open-ended forfitting over or to the container valve 18.
  • the rods 120a extend out of opposite sides of the nozzle piece, set in from the inlet end 120b.
  • the main body of the nozzle piece is right-angled and has a correspondingly-shaped conduit inside which leads to the outlet 120c.
  • the outlet 120c has ribs around it for improving the connection or seal formed with the tube 20.
  • Figure 7 shows how the shape of the inlet end 120b is adapted to fit the container valve 18.
  • the applicator 100 is connected to the container 10 by aligning the applicator 100 and container 10 on a common central longitudinal axis and screwing the applicator until a tight connection between the screw threads 16, 132 is achieved.
  • the container 10 should be shaken before use, although the exact point at which this is done does not particularly matter.
  • the tube 20 is fitted onto the nozzle outlet 120c and the sidewalls 116 removed from the applicator 100. If gloves have been provided within either chamber, then the gloves may now be put on.
  • the tab 122 is then torn out of position, breaking the frangible connections 124 and freeing the trigger handle 112 for use.
  • the end of the tube 20 is aligned with the intended location for receiving Pll foam, with the container 10 inverted such that the handle portion 104 is lower than the cap portion 102.
  • the handle portion 104 can then be squeezed, forcing the trigger element 112 into contact with the top of the nozzle piece, which in turn depresses the container valve and dispenses Pll foam through the nozzle piece and tube 20.
  • the nozzle piece 120 is adapted to provide enough of a seal to ensure the composition must exit via the end of the tube 20 rather than at an earlier point in the flow path.
  • the user can cease squeezing handle portion 104. This allows the container valve 18 to shut and the nozzle piece 120 and moveable handle 112 return to (or are biased back into) their default positions. The dispensing operation may be repeated as needed.
  • the tube 20 can be pivoted down and clipped into the clip 110.
  • the sidewalls 116 can be pushed back into either side of the applicator 100, between the handle portions 112, 114, to secure the moveable handle 112 against operation.

Whilst similar features to the first embodiment are only referred to in passing, or not referred to directly at all, this is for brevity only and details equivalent to the first embodiment are to be assumed unless otherwise indicated.
  • the applicator 200 has handle portion 212, 214 which are substantially similar to those of the first embodiment.
  • a tab 222 is provided between corresponding walls 213a, 214a of the handle portions 212, 214, although in this embodiment the tab 222 is longer and extends beyond the upper ends of each handle portion 212, 214 such that the ring section formed by the aperture and strip 226, 228 is visible above the handle portions.
  • this merely illustrates the option to have different sizes of tab, and it is preferred that the tab is flush with the top of the applicator or that it terminates at a position below the top of the applicator.

  • the flange 218 around the nozzle piece 220 has a C-shaped cross-section when viewed from above, rather than a U-shaped cross-section. Whilst this provides a slight gap compared to the first embodiment, the nozzle piece 220 is still adequately shielded against accidental knocks.
  • a lever 234 is shown in the cap portion 202. It will be appreciated that part of the cap portion 202 forms the lever 234. Sides of the lever 234 are connected to the rest of the cap portion via frangible connections 236. A lifting tab 238 is provided at a free end of the lever 234. The lifting tab 238 lies below the rim of the cap portion flange 208. The other end of the lever 234 is hingedly connected to the cap portion 202.

  • the lever 234 does not need to be frangibly connected to the cap portion 202.
  • the lever may have one or more protrusions which engage corresponding recesses in the cap portion, or another arrangement which permits the lever to be releasably secured in both container-engaging and containerdisengaging positions at will, rather than single use. That is, the lever may be configured to allow the applicator to be secured to a different container after detachment from the first container, rather than immediately recycled.
  • the applicator 200 is similar to the first embodiment.
  • the applicator is first snap fitted to the container by coaxial movement onto the top of the container 10’.
  • the tab 222 is torn out in the direction indicated by arrow A, after removal of the sidewalls (in embodiments where sidewalls are provided).
  • the moveable handle portion 212 is squeezed or pivoted towards the other handle portion 214, and this causes the trigger element 213b to depress the nozzle 220 and dispense composition from the pressure container 10’. Removal of the squeezing or pivoting force allows the moveable portion 212 to relax back to its default position in the reverse direction to arrow B.
  • the lever 234 is lifted via the lifting tab 238 whilst applying suitable force in the direction of arrow C to break the frangible connections 236.
  • the lever 234 may flex as shown in Figure 15 but the applicator material is resilient enough not to snap. Suitable opposing force may be used to keep the container in position, for example by pressing it down onto a table. Once done, the applicator can then be lifted away from the container 10’ in the direction of arrow D.
